Description

I have a virtual machine with Rudder server 2.4.

After some time running (a couple of hours), the VM is full of cf-execd (tens of them), eventually leading to really hight CPU consumption and even OOM Killer going wild.

This has been "worked around" by adding a promise in the Rudder common Technique to kill cf-execd automatically when too many instances are running. This is not a fix, but will avoid most of the main issues encountered. See #2661.

For some reason, the Vagrant VM holds bad promises, editing the /var/spool/cron/crontabs/root
It is unclear where this promises come from, and when we mount the VM Vagrant, it overrides the promises located on the host machine on /var/rudder/cfengine/inputs
Regenerating promises correct the promises on the Vagrant VM

If I understand, this is due to the configuration of a Vagrant VM for dev, which use a specific /var/rudder/cfengine/inputs shared by the host machine.

Whatever, this issue should be moved to the next run
